Hello, I use Linux Mandriva 2006 and as I describe in subject with tcpdump 50% of received packet are missing! I provide many test and it's also the same I capture 1/2 of received packets.
[user ~]$ uname -a Linux hostname 2.6.12-12mdksmp #1 SMP Fri Sep 9 17:43:23 CEST 2005 i686 Intel(R) Xeon(TM) CPU 3.00GHz unknown GNU/Linux [user ~]$ /usr/sbin/tcpdump --version tcpdump version 3.9.2 libpcap version 0.9.1 Usage: tcpdump [-aAdDeflLnNOpqRStuUvxX] [-c count] [ -C file_size ] [ -E algo:secret ] [ -F file ] [ -i interface ] [ -M secret ] [ -r file ] [ -s snaplen ] [ -T type ] [ -w file ] [ -W filecount ] [ -y datalinktype ] [ -Z user ] [ expression ] [user ~]$ /usr/sbin/tcpdump -i eth1 >test.dump tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth1, link-type EN10MB (Ethernet), capture size 96 bytes 923 packets captured 1846 packets received by filter 0 packets dropped by kernel Any idea?
